South San Francisco, CA: 7/31/2007:

SOUTH SAN FRANCISCO, CA--(Marketwire - July 31, 2007) - Michael R. Wyman, Chairman of FNB Bancorp (OTCBB: FNBG) and its subsidiary, First National Bank of Northern California, announced today that Director Neil J. Vannucci has submitted his resignation from the Board of Directors (including subcommittees of the Board of Directors) of FNB Bancorp and First National Bank of Northern California, effective August 24, 2007.

In his letter to the Board, Mr. Vannucci stated, "I have been privileged to serve as a director of this wonderful Bank for almost twenty years and I am very grateful for that opportunity. I'm confident that the board and management will continue the tradition of providing a great working environment for our employees, offering outstanding service to our valued customers and rewarding the investment of our shareholders. It's simply time for me to enjoy full-time retirement."

"Neil has been an outstanding director over the past nineteen years. His guidance, independence and numerous contributions have played a very important role in the Bank's success," said Wyman. Lawrence Vannucci, Mr. Vannucci's uncle, was one of the six original founders of the Bank in 1963. Wyman added, "While we understand Neil's desire to enjoy retirement, his leadership and active participation as a board member will be missed. For all his efforts on behalf of the Bank, we wish Neil and his family the best."
